Grid and header menus share ely_office::menu with ElyDoc. Each item's availability is the kernel's state for the exact command it runs (patch 0045). Patch 0046 lets a header select its row or column while a shape is selected or its text is edited: the view shell ends the drawing edit, keeps the typed text, leaves drawing mode, then marks. Ely no longer sends Esc first. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
